VAG'IN'AL SYRINGE;

Specification of Letters Patent. Patented Oct, 18, 1910.

Application filed December 24, 1909. Serial No. 534,893.

To all whom it may concern:

Be it known that I, FRANK A. NEVEU, a citizen of the United States, residing in the city and county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Vaginal Syringes; and I do declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being. had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in vaginal syringes, my object being to provide a device adapted to produce a continuous circulation of liquid from the cylinder to the parts to be treated and from the lat ter to the cylinder. In this respect the object is the same as that set forth in Letters Patent No. 930,312, dated August 8rd, 1909. However, in my present invention certain improvements" are employed which make the device considerably better than the construction disclosed in the said patent. .In my present construction the nozzle of the device is located at one side of the center, the said nozzle being divided by a partition extending forwardly from the forward end of the cylinder, the said partition being integral and continuous with the wall of the cylinder on the side where the nozzle is located. One compartment of the nozzle communicates directly with the forward extremity of the cylinder chamber while the other compartment communicates with the rear extremity thereof through an opening hav ing a diameter greater than the thickness of the cylinder piston, so that the cylinder may be filled with liquid when the piston is at its rearward limit of movement by introducing the liquid at the outer end of the nozzle. This nozzle is provided with ribs for retaining a shield formed of soft rubber and longitudinally adjustable upon the nozzle for regulating the depth of insertion and closing the vaginal cavity to prevent the escape of liquid except by circulation through the instrument, as heretofore explained.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is an elevation of my improved device. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a fragmentary view of the rear part of the cylinder showing the piston at its rearward limit of movement. Fig. 4 is a cross section taken through the cylinder. Fig. 5 is a simi lar section taken through the nozzle.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the cylinder or body of the device which is equipped at its rear end with a head 6 provided with a stuffing box ,7 through which passes the stem 8 of the piston 9, the latter being reciprocable within the cylinder.

The rear extremity of the cylinder, close to the head, is provided with an opening 10 communicating with a passage 12 which is formed by a sort of half tube 13 projecting from one side of the body of the cylinder. This passage 12 is in alinement with and merges into a compartment 14 of a nozzle 15 leading forwardly from the forward extremityof the cylinder and having a centrally located partition or septum 1 6 dividing the nozzle into two compartments 1 1 and 17, the compartment 17 communicating at its rear extremity with the forward end of the cylinder by way of an opening 18.

The forward extremity of the nozzle may be closed by a rubber cap 19 which fits closely thereover when the device is not in use. This nozzle is equipped with exteriorly circumferential ribs 20 which form stops to retain theshield 21 in the proper position of adjustment upon the nozzle. These ribs constitute an important feature, since they are accurately spaced to correspond with the thickness of the part 22 of the shield which engages the nozzle. Hence, when the shield is adjusted it will retain its position and resist considerable pressure without movement. Its object is, as heretofore indicated, to determine and limit the depth or distance of insertion of the nozzle and when the lat ter has been inserted to the desired depth, the shield is in close and perfect engagement with the mouth of the vaginal cavity, whereby further insertion, as well as leakage, is prevented.

Preparatory to the use of the device the cylinder is filled with the properly medicated liquid, the piston being withdrawn to the rear extremity of the cylinder, leaving the port 10 partly uncovered forward of the piston. The properly medicated liquid is ste m then introduced in the compartment 14 of the nozzle and enters the cylinder forward of the piston. In this manner the cylinder may be filled with the desired solution. As soon as this is done, the nozzle is inserted in the cavity to be treated, to the depth permissible by the location of the adjustable shield. The piston is then moved forwardly whereby the liquid in the cylinder is forced out through the compartment 17 of the nozzle into the cavity to be treated, whence it is caused to automatically circulate or flow through the compartment 14, back into the cylinder through the opening 10 in the rear of the piston, then as the piston is moved rear-wardly, the liquid is forced into the cavity to be treated through the compartment 12 and withdrawn from the cavity through the compartment 17 of the nozzle. In this way a circulation of the medicated liquid is maintained, the said liquid being forced into the cavity by the movement of the nozzle in either direction and drawn into the cylinder by the flow of the liquid from the cavity, as will be readily understood.

Having thus described my invention, what I claim is:

1. A vaginal syringe comprising a cylinder, a piston therein, a nozzle projecting forwardly from one side of the forward extremity of the cylinder, the said nozzle being separated by a suitable partition into two compartments, one of which communicates at its rear extremity with the forward end of the cylinder at one side thereof, while the other extends longitudinally with the first named passage in direct alinement with a passage formed outside of the body of the cylinder and communicating with the forward end of the cylinder by an opening which is of such size as to be partly uncovered forward of the piston when the latter is at its rearward limit of movement.

2. A device of the class described, comprising a cylinder, a piston mounted to reciprocate therein, a nozzle extending forwardly from one side of the forward end of the body of the cylinder and having a partition separating it into two passages both of which are open at the forward extremity of the nozzle, one passage communicating at its rear extremity with the forward extremity of the cylinder on one side thereof while the other extends longitudinally with the first named passage in direct alinement with a passage extending rearwardly outside of the body of the cylinder but communicating with the rear end of the latter by a suitable opening whereby the medicine is caused to be automatically and alternately drawn into the cylinder, forward and backward of the piston, substantially as described.

3. A device of the class described, comprising a cylinder, a piston mounted to reciprocate therein and having a stem protruding through an opening formed in the rear extremity of the cylinder, the latter be ing equipped with a stufling box to form a liquid-tight joint around the said stem, the device having a nozzle extending forwardly from the forward end of the cylinder and longitudinally divided into two passages, one of which is in communication at its rear extremity with the forward end of the cylinder, while the other is in direct alinement with and merges into a passage extending rearwardly on the outside of the body of the cylinder and communicating with the rear end of the latter through a suitable opening, and a shield applied exteriorly to the nozzle, the latter having circumferential ribs so spaced that the portion of the shield engaging the nozzle, shall fit closely between any two ribs of the nozzle, for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
